When booking for the event there is an option to 'Save & add another person'. Multiple people can be added with varying ticket options.
When all attendees have been added, the person booking is then presented with a subtotaled view and can pay for the entire booking in one transaction.
Important to note: All required fields WILL be required for each attendee. While all details may not be necessary for each attendee, we want to be sure to capture each attendee individually to provide accurate attendee counts.
